I'm having a base class defined in my app

Something like,

using System;



public class BaseClass

    {

       public virtual void Method2() {Console.WriteLine("base2");}

       public virtual void Method1() {Console.WriteLine("base1");}

    }

public class Derived1 : BaseClass

    {

       public override void Method2() {Console.WriteLine("derived1-2");}

       public override void Method1() {Console.WriteLine("derived1-1");}

    }

    public class Derived2 : Derived1

    {

       public override void Method1() {Console.WriteLine("derived2-2");}





    }

public class Program

{

    public static void Main()

    {

        var obj = new Derived2();

        ((BaseClass)obj).Method2();

        Console.WriteLine("Hello World");

    }

}

Say I need to access the Method2() of my very first BaseClass. Even after typecasting it to ((BaseClass)obj).Method2(), I'm still getting derived1-2 while I'm expecting base2'.

How do I do that ?

I completely agree with the comments: it sounds like the behaviour that you require would need you to re-think your classes - possibly inheritance is not the best solution in this case. It depends what you're trying to do; you could obviously just do this:

var obj = new BaseClass();

((BaseClass)obj).Method2();

Console.WriteLine("Hello World");

My guess would be that what you actually want here is some form of injection; for example:

public class BaseClass

{

    private readonly IFunctionality1 functionality1;



    public virtual void Method2() { Console.WriteLine("base2"); }

    public virtual void Method1() { this.functionality1.Method1(); }



    public BaseClass(IFunctionality1 functionality1)

    {

        this.functionality1 = functionality1;

    }

}

public class Derived1 : BaseClass

{

    public Derived1(IFunctionality1 functionality1) : base (functionality1)

    {



    }



}

In this case, you might find that inheritance isn't even required anymore.
